This is generally the order that would cause me to end up with some cities not getting Aqueducts until late Renaissance. But happiness-constrained Aqueducts aren't necessarily better than Workshops, and I have other techs I want to get, so I'll sometimes do things like University -> Observatory -> Workshop -> Aqueduct. At this point I shift a bit more to food and cities start growing again, and Aqueducts become more useful. Once Universities are up, I have specialist slots, which means each city effectively has two more "good" tiles that I actively want to work. These cities are thus capable of getting their Universities up in reasonable time, despite being small. Since they aren't growing, they must be working non-food tiles, which generally means I have a lot of hammers relative to pop at this stage of the game. So I have these small cities, some of which are stagnating as I hit Education. In this scenario, Aqueducts would be good in some cities but useless in others. The National College city will grow more, since it usually has more good tiles and needs to build wonders - this city likely works all +food tiles. For some cities this will only be about pop 5 or 6, especially early on when borders haven't fully expanded. My general approach is to try to grow each of my cities to the size where they can work all their resource tiles, maybe an extra Mine, and no more. Max growth in every city isn't an option, so I need to pick and choose where I grow. In terms of what my empire management actually looks like: in the early-mid game, happiness is usually a big constraint. But only in some cities, so it's hard to say how valuable the tech is. If the tech wasn't off the Education beeline, I would build Aqueducts earlier. I guess it's more that I don't like taking the time to get Engineering. It's just that other stuff is good too - I really want to get my GS points ticking ASAP, and I also want to get to Renaissance ASAP for Rationalism.
